That's what I liked about it, the different setting and the accents that is, but I thought that will-o-the-wisps were generally to be avoided.

From general mythos, yeah, they were to be avoided. In some they were the spirits of the departed who wanted to help their kin, so it's not a stretch what they did, just not the normal mythos.

I still need to see this movie. I can't wait till I finally can!
